Numa Pass Trail

Overview

Numa Pass is a high, wind‑brushed saddle on the famed Rockwall, delivering sweeping views of Floe Peak, the limestone cliff band, and fire‑regenerated slopes below. Expect a difficult outing with long, steep grades and meaningful elevation gain.

How long is it, really?

The signed Numa Pass segment itself is about 6.0 miles one way with roughly 2,750 ft of climbing and some descent along the way. As a day hike, most people approach from Numa Creek (roughly 4.3–5.6 miles one way to the pass depending on where you turn around) for a strenuous out‑and‑back. Coming from the Floe Lake trailhead is far longer (12–14 miles one way to the pass) and is typically done as an overnight, tagging the pass from camp at Floe Lake.

What it’s like

Lower miles climb through forest and burn zones before breaking into subalpine meadows and open slopes near treeline. The higher you go, the bigger the payoff—panoramas of the Rockwall, hanging glaciers, and the turquoise basin around Floe Lake. Water is reliable in the valleys but scarce right on the pass—tank up and treat before you leave the creeks.

Best time to hike

Prime hiking runs mid‑July through late September when lingering snow finally melts out and creek crossings are reasonable. September is typically drier with cool air and golden larches—bring layers for early frosts or a surprise dusting of snow. Outside June–October, treat this as winter backcountry travel with avalanche hazards.

Permits, rules, and logistics

A park entry pass is required. Overnight trips need a backcountry camping permit, and you must use designated camps (no random camping); campfires aren’t permitted in the backcountry. Food must be stored in provided lockers or on cables. Pets are allowed but must stay leashed at all times.

Hazards and trail conditions

This is prime grizzly and black bear habitat—carry bear spray, make noise, and give wildlife space. Expect changing mountain weather, possible downed trees, and shifting conditions in fire‑affected areas. Avalanche risk exists from early winter to early summer above treeline. Cell coverage is unreliable—carry a satellite communicator and leave a trip plan with a reliable contact.

Getting there

Both Numa Creek and Floe Lake trailheads sit along Highway 93 South between Banff and Radium. Numa Creek is the most direct day‑hike approach to the pass; Floe Lake is the scenic backpacking approach and an excellent sunrise side trip from camp.
